Pour into 5 gallon cooler the vodka, tequila, rum and everclear with the Gatorade and Sprite. Alternate alcohol/non-alcohol for better mixing. Dissolve the 4 cans of concentrate in a seperate pitcher with water until liquid. Add to the cooler and stir well. Chill all the ingredients before you put them in and then chill the cooler until the party. For extra flavor, add as much Kool-Aid and sugar as you like.
